To aZZ whom it may concern:

Be it known that I, WILLIAM T. Connnr, a citizen of the United States, residing at Cambridge, in the county of Middlesexand State ofMassachusetts, have invented a new and useful Shingle, of which the following is a specification; p K

This invention relates to shingles, and more particularly to locks for flexible shingles. I

The object of the invention'is to provide a shingle of this character so constructed as to cause the interlocking of the various shinglesand preserve the relation between :lem and which avoids curling of the lower other object is to so constructa shingle as to cause it to lie "in close contact with the roof and sub'acent Shingles producing a leak roof 1-00 of long hfe.

Anot er object is to provide a shingle across the entire butt which is formed 0 the same material as the shingle and as an addition 'thereto avoiding the necessity of cuttinginto/the shingle and the consequent weakening thereof and which may be quickly put implace and presents when applied a neat appearance and at has great Strength.

ith the foregoing and other objects in view which will appear as the description roceeds, the invention resides in the com ination. and arrangement of parts and the details of construction hereinafter ,de scribed and claimed, it bein understood that changes in the precise em odiment ofthe invention herein disclosed, may be made within the scope of what is claimed without de arting from the spirit of the invention.

the accompanying drawings Figure 1 represents a plan view of a portion of a roof formed from shingles constructed in accordance with this invention.

Fig. 2 is a bottom plan view. Fig. 3 is a plan view of one of the shingles with the locking tabshown in open unfolded position.

Fi 4 is a transverse section taken on the line of Fig. 2; and

Fig. 5 is a'section taken on the line 5-5 of Fig. 2.

In the embodiment illustrated the shingle 1 constituting this invention is constructed of the usual asphaltic composition, metal or otherflexible material and is shown made substantially rectangular or diamond shaped in accordance with-the general practice although it will be understood that the shape tabs '5 and 6 which with the butt of the shingle form' a flap 2 foldable along the dotted line 3 to lie when in operative position under the body portion of the shingle,

.the tabs .4 and 5 being pointed as shown at part of the shingle stren thens the shingle and provides when inter ockingly engaged with the adjacent shingles a secure lock.

The locking 'fiap 2 extends across the entire butt of the shingle and avoids all necessit of. cutting into the shingle such as is or inaril found necessary with shingles of this 0 aracter. be quickly put into place on the roof and wvhen the shingles are connected the securin means are invisible .as shownin Fi 1. Lin shingling a roof with flexible shing es 1 embodying this invention, the shingles are laid diagonally as shown in Figs. 1 and 2. Each course is laid by placing the shingle of the next upper course over a shingle of the next lower course in position. for the corners The look so formed canof the shingles of the lower course to be inserted between the ends of flap 2 of the shingle of the upper course as shown in Fig. 2 so that the shingles are all interlockinglyconnected thus preventing curling of thefshingle edges and providing a leak proof r00 Various changes in the form, shape, proportion and other minor details of construction may be made without departing from the principle or sacrificing any of the advantages of the claimed invention.

I claim:

An individual diamond-shaped shingle having unbroken ed es and its butt extended laterally at both e ges to form a locking tab, said tab being foldable under the body of the shingle to provide pockets to receive and interlockingly engage the edges of ad jacent shingles, each end of saicl tab being In testimony that I claim the-foregoing inclined inwardl I in opposite directions as my own, I have hereto aflixed my s1gna from its center, 't e inclined inner portions ture in the presence of two witnesses. conforming to the adjacent side ed es of the WILLIAM T.
